What are the different types of lung crackles?

There are four broad categories for lung crackles that doctors use to better classify their observations. Some conditions are only associated with certain lung sounds, so knowing what kind of crackling your lungs have helps the differential diagnosis. Crackling in the lungs when breathing out or in falls into one of the following groups: 1 Wheezes: A wheeze is a sort of high-pitched sound that comes from air trying to get through a narrowed passageway. Occasionally, wheezing can be pronounced enough that your doctor can hear it without a stethoscope. 2 Rales: Rales have a bubbling, clicking, or rattling sort of sound that occurs when you inhale. They tend to happen when air enters an otherwise closed space. Rales can be further subcategorized as moist, dry, fine, or coarse depending on the nature of the sound. 3 Stridor: Stridor is similar to wheezing but originates closer to the trachea and has a higher-pitched, almost musical quality. Stridor sounds are more likely to be the result of something obstructing the trachea or the back of the throat, and the sounds are more pronounced when inhaling. 4 Rhonchi: Rhonchi falls under the wheezing category, but its sounds resemble snoring and happen in the larger airways. During rhonchi sounds, airflow may be blocked or is otherwise “rough” during its passage.
